A Yemeni boy wearing a Syrian flag flashes the victory sign during a march demanding the dismissal of ex-regime commanders from powerful military positions in Sana’a, Yemen, 17 May 2012. According to media reports, thousands of Yemeni protesters took to the streets to ask Hadi to remove former president Saleh’s relatives and loyalists from powerful military positions, a day after US President Barrack Obama signed an executive order giving the Treasury Department the authority to freeze any Yemeni official’s assets if found trying to hinder the implementation of a Gulf-brokered and US-backed power transfer deal in Yemen.
